SmythOS
SmythOS is an orchestration platform for designing, observing, and deploying AI agents. Its Studio provides a drag-and-drop workspace for agents and workflows, while Agent Weaver can create, troubleshoot, and revise workflows from conversational prompts. Agents can be deployed through chat, APIs, webhooks, MCP servers, and ChatGPT, or exported to run locally. Connections include Slack, Trello, GitHub, and Stripe, alongside OpenAPI and Postman collections. The platform supports models from OpenAI, Anthropic, Hugging Face, and customer-provided sources. Deployment options include local, on-premises, VPC, and SaaS; the maker describes access controls and isolated agent contexts. A free plan is available, and paid plans start at $39 a month. Fast API call allowances vary by plan, from 100 per day on Builder to unlimited on Enterprise. Built-in model use is charged separately according to usage. SmythOS runs on web, Windows, macOS, Linux, API, and self-hosted environments, and is headquartered in Houston, Texas.
